Badminton ace Nguyen Tien Minh won his first London Olympics encounter, coming back from behind to beat Belgian Tan Yuhan 2-1 on Sunday.
The 10th-seeded Vietnamese made a lot of mistakes and was always behind the Belgian rival in the first set before losing it 17-21.
However, Minh, ranked 11th in the world by the Badminton World Federation (BWF), had the measure of 54th-ranked Yuhan in the remaining sets.
Minh won the second set 21-14 before cruising to victory by winning the decider 21-10.
In his next Group D match on Tuesday, the Vietnamese will clash with Indian player Parupalli Kashyap. The Indian is currently standing in the 21st position in the BWF rankings and Minh is expected to have a tough match.
There are 16 groups in the first round and only the best player of each group will advance to the second round.
